Let me provide more information. We have 3 gluster nodes running with sharding activated. Node1: CentOS 7.5 - Glusterfs 3.12.6 Node2: CentOS 7.5 - Glusterfs 3.12.6 Node3: CentOS 7.5 - Glusterfs 3.12.6 Now we updated Node 3 from CentOS 7.5 to 7.6 which caused a reboot. Glusterd Version changed from 3.12.6 to 3.12.15 Node1: CentOS 7.5 - Glusterfs 3.12.6 Node2: CentOS 7.5 - Glusterfs 3.12.6 Node3: CentOS 7.6 - Glusterfs 3.12.15 Afterwards gluster heal daemon keeps resyncing specific shards on bricks on Node1 and Node2. Always the same shards.
